Abstract: Objective To observe the value of modified endovascular snare system for removing fusiform inferior vena cava filter(IVCF)with retrieval difficulty.Methods Data of 30 cases after implantation of recoverable fusiform IVCF and finally removed using a modified endovascular snare system were retrospectively analyzed.The X-ray exposure time and operation time for removing IVCF,and the adverse reactions during procedures,as well as reexamination results of color Doppler ultrasound and complications during 1-6 months'follow-up were recorded.Results IVCF was successfully removed in all 30 cases,and the technical success rate was 100%(30/30).The median X-ray exposure time was 5 min,while the median operation time was 31.5 min,without obvious discomfort during the procedures.Color Doppler ultrasound showed no obvious stenosis nor complication such as mural thrombosis in inferior vena cava during follow-up.Conclusion Modified endovascular snare system was effective and safe for removing fusiform IVCF with retrieval difficulty.
